Use isWikiWord() to test a word as it would appear in a wiki page, with or without brackets, isNakedWikiWord() tests this for words without brackets ("naked" words) as they appear now everywhere internally in the database.

The use of isCcWikiWord() should be clear and wikiWordToLabel() strips brackets from a word (but doesn't test if it is a valid wiki word). The name of this last function may change in the future.
